Metro 2033 Redux is a survival horror game created by 4A Studios. Metro Redux is the remastering of Metro 2033 and Metro: Last Light. In Metro 2033, the player assumes the role of Artyom, a teenager who is throwwn into the middle of a conflict between humanity and a new breed of homosapiens known as "The Dark Ones." Set in a post-nuclear setting, the player must travel via the underground metro tunnels, fighting hordes of mutants, monsters, and bandits.

Metro Redux takes advantage of the new 4A engine, which is considerably optimized compared to the original Metro 2033 engine. Players can now experience Metro 2033 Redux with new lighting, textures, level re-designs, and many other improvements that allow the game to flow better. The combat system from Metro Last Light (Spartan) is available for playing through Metro 2033. However, this game movie is played in Survival, the original combat system designed for Metro 2033. Survival mode creates an ammo shortage, requiring players to conserve ammo and currency in order to survive the harsh metro conditions.
